WEATHER-STRIP FOR DOORS.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed October 23, 1908. Serial No. 459,168.

To (1M whom it may concern:

Be it known that I, lloiin'n l ])AV1S, a citizen of the United States, residing at East Aurora, iu the. county of Eric and State of New York, have in\'e1'1ted a new and useful linprovcmont in \Vcather- Strips for Doors, of which the following is a spccification.

This invention relates more particularly to weather-strum of that type which are hinged to the lower portions of doors and bear upon the door sills for closing the space between the door and its sill when the door is shut, and which, when the door is opened, are raised off of the sill, thus permitting free movement of the door over the floor.

The object of this invention is to provide a weather-strip of this kind which is composed of few parts of simple construction and can be made and applied at small expense, and which will be effective in operation and will not interfere with the door being opened to its full extent.

In the accompanying drawings: Figure 1 is a fra mentary front elevation of a door and its frame provided with a weather-strip embodying the invention. Fig. 2 is a fragmentary perspective view of the same, on an enlarged scale, showing the door slightly ajar. Fig. 3 is a fragmentary vertical crosssection of the same, showing in solid lines the position of the weather-strip when the door is closed, and in dotted lines, its position when the door is opened. Fig. 4 is a similar View, showing the position of the weather-strip when the door has been opened into engagement with its frame. Fig. 5 is a fragmentary horizontal section of the same, showing the door open and the end of the weather-strip at the hinged side of the door enga ing the door frame.

Li to letters of reference refer to like parts in the several figures.

A represents a door of ordinary construction, B the door frame and C the sill therefor. The weather-strip is arranged on the inner side of the door adjacent to its lower edge and consists of a fixed cleat or strip D which is secured horizontally on the door by screws or other suitable securing means, and a movable strip E which depends from the lower edge of the cleat D and is hinged thereto-so that it can swing toward and from the sill or floor. A flexible strip F of felt or other suitable material is secured to the skle of the movable strip I), which is next to the face of the door, and extends dowl'iwardly a short distance beyond the lower edge of the hinged strip E. This projecting portion of the flexible strip is adapted to bear on the sill and fold under the lower edge of the hinged strip E so as to effectually close the space between the same and the sill when the door is shut.

G represents a spring which tends to swing the hinged strip E upwardly away from the sill or floor and hold it in the substantially horizontal raised position shown in, Fig. 2 and by dotted lines in Fig. 3. This spring consists of a spring wire extending parallel with and close to the joint be tween the cleatand hinged strip and having oppositely bent ends 9 which are respectively secured to the cleat D and hinged strip E adjacent to their ends. The spring rod between its bent ends extends through the knuckles of hinge leaves secured to the cleat and hinged strip, thus constituting the pivot pin or pintle for these leaves and together therewith forming the hin es H for connecting the hinged strip E and cleat D. The ends of the spring wire G normally ex tend at such an angle to each other that the one secured to the hinged strip E will extend outwardly from the door, so that when this hinged strip is swung downwardly the spring wire will be twisted or placed under torsional strain and will swing the hinged strip upwardly when permitted to do so. The spring wire thus performs the double function of a hinge rod for the hinged strip and a spring for raising the same from the floor when the door is opened, and this con struction serves also to hold the spring wire in place parallel with and close to the joint between the two parts of the weather-strip where it will be inconspicuous and will not detract from the neat appearance of the weather-strip.

A lever arm I is preferably secured at one end to the end of the hinged strip E at the outer edge of the door and extends beyond the edge of the door and is. adapted to engge and slide u wardly on the frame B when the door is eing closed, thereby swinging the hinged strip E down against the action of the s ring G into its vertical position, shown in ig. 3, in which it closes the space between the door and its sill. As long as the door remains closed, the arm I bearing against the frame B holds the strip E in its vertical position. When the door is opened, the arm I moves out of engagement with the frame B and frees the hinged strip E which is then swung up to its raised position by the spring G. The upward movement of the hinged strip is preferably limited by a stop K secured to and projecting outwardly from the cleat D.

In order that the weather-strip may not interfere with the opening of the door to its fullest extent, the outer corner L of the hinged strip E at the end thereof next to the hinged edge of the door is cut away at an angle, see Figs. 1 and 5, so that if the door is opened far enough this inclined corner will engage the frame B and cause the hinged strip to swing downwardly to its vertical position if the door is opened any farther. The felt strip F preferably projects beyond the inclined corner of the hinged strip E so that it willv close theend of the space beneath the door. The projecting end of the felt strip also assists in turning down the hinged strip when the door is swung wide open and preventing the same from lnarring the frame B.

I claim as my invention:

A weather-strip for doors comprising a fixed strip secured to the door, a movable strip connected with said fixed strip and provided with a piece of flexible material, the inner end of said movable strip being cut away leaving said flexible material. exposed, and means for normally holding said movable strip in a raised position, substantially as set forth.

Vitness my hand, this 15th day of June, 40
